Collins did distribute a letter that provided a general clue as to why AAI may have closed after 30 years of uniting families with children. The letter thanks staff members, parents and sponsors. It referenced "extremely large financial challenges over the past few years."

"I think it's a tragic thing," said Peter Ripley, son of the woman who founded AAI. Marrily Ripley opened the agency in 1983 and recently retired.

He expressed concern for how the sudden closure will affect current clients.

"Everything is in limbo, but I think if they just hold on and keep the faith I think things can fall through and things can work out," he said.

Families often wait up to three years for the entire adoption process to unfold and take their child home. AAI does not reveal on its website how many clients it now has.
